[Western Crossover] The Game Descends into Reality

Luo Lan transmigrated along with a gaming platform. He soon discovered that he could transform into characters from the game's library:

A white-haired, golden-eyed monster hunter; an undead warrior born to link the fire; a machine with humanity; an assassin devoted to upholding a creed.

"So, what's the price?"

I'm sorry, sir. The games are coming to life in the real world...

P.S. A Steam secret-identity story. No identity reveals, no romance, easy to read, and even readers who haven't played these games should be able to follow along (probably).

Theme: Fight crime and root out evil
